'flb all whom it may concern:

'Be it known that I, JAMES S. LYNCH, a

citizen of the United States, residing at Citronelle in the county ofMobile and State of Alabama, have invented certain new and usefulImprovements in Revolving Cultivator-Hoes, of which the following is aspecification, reference being had to .the accompanying drawings.

This invention relates to agricultural apparatus and moreparticularly'to that class of devices known as hoes.

The main object of this invention is to provide ahoe which willefiectually shear the surface of the soil and at the same time pulverizethe same thoroughly.

Another object of this invention is to have the device as simple aspossible so that it may be readily and cheaply manufactured, and so thatits parts will be arranged so as to permit easy inspection and repair.whenever the same is desirable.

Other objects of this invention will become apparent as it is more fullyset forth.

In the accompanying drawings which illustrate by way of example anembodiment of this invention, Figure 1 represents a view in elevation ofa hoe embodying this invention. Fig. 2 is a sectional view taken throughthe main wheel of Fig. 1. Fig. 3 is a detail of the blades of a hoe; andFig. 4 is adetail of one of the standards used in this device. J

Similar reference characters refer to similar parts throughout thedrawings.

The reference. character 1 represents the main wheel of the device inquestion, which is provided with a plurality of toes 2 on the outsidethereof. The main wheel is provided with'an annular gear 3 on itsinteriorsurface, and is secured to its hub 4 by means of a side plate 5,as is'clearly shown in the drawings. 1

6 is a suitable axle for the hub and has a holder 7 provided thereon andfastened thereto by means of a set screw 8. The holder 7 is providedwith holes 8' and 9 respectively therein for the purpose of permittingbolts 10 and 11 respectively to extend therethrough and support thepinions 12 and, 13 thereon.

A central gear 14 is loosely mounted on the shaft 6 and is arranged toengage with the gear 12,-as is clearly shown in the drawings. Asprocketlfi is mounted on the hub of the gear 14 and rigidly securedthereto, so as Specification of Letters Patent. Application filedDecember 22, 1911. Serial No. 557,372.-

to move therewith. The gear 12 is arranged to engage with the gear 13,whichfin turn engages with the annular gear3 and is actuated thereby,when the wheel 1 is rotated. I

\Loosely mounted on the shaft 6 a bandle member 16, that is providedwith suitable braces 17 that are'arranged to hold a pair of arms 18 inrigid relation thereto, as is clearly shown in Fig.- 1. A rod 19 extendsthrough the braces17 and the handle member Y16 and \is arranged toengage with a pair of slotted members 20 that extend on either side ofthe wheel I andkeep a draft hook 21 in a position to suit the meansdrawing the device over the fields or the like to be hoed. Arms 22extend from the shaft 6'and interconnect with the draft hook. 21 and themembers 20. 1

' The arms18. are provided with holes 23, in their lower portions, ofsuitable size to permit a shaft 24 to freely rotate therein.

shaft and is actuated by a chain 30, which in turn is operated by thesprocket 15.

The general. position and angle of the knives 27 are, as shown in Fig.3. The knives on each side are arranged toshear away from the centralportion of the shaft.

The general operation of the device is as follows :When the wheel 1 isrotated, its annular gear 3 rotates with-it and actuates the gear 13,which in turn rotates the idler 10, and thereby actuates the gear 14,and

causes the sprocket 15 to rotate and operate the knives 27, through thevarious parts of the transmission mechanism used in connect-iontherewith. The rate of rotation of the knives is fixed by using suitablegearing. As the knives rotate the points 26 engage with the ground andslightly break up the same and provide furrows for the knives.

to follow into. The knives 27 then cut diagonally into the ground andshear it as it were and slightly turn it over in a manner similar tothat of the hoe. As the succeedas many modifications in the constructionaction to the device, but also a substantial ing knives and standards orparts of the same engage with the soil, they turnthe same over more andpulverize it thoroughly. By arranging the standards 25 as is 'clearlyshown in the drawings, a means is provided for not only providing thenecessary digging bracing means for the knives themselves, and byarranging the standards with threaded ends, and attaching the knivesthereto in the manner shown and described, an arrangement is providedwhich permits the ready removal orinterchanging of these various partswhenever the same is desirable.

Obviously it is not desired to limit this application for patent in anyother way otherwise than necessitated by the prior art,

thereof may be made without departing from the principles thereof andcoming within the scope of the appended claims.

Having thus vdescribed this invention, what is claimed is 1. In. adevice of the class described, a shaft, a plurality of spirally disposedknives, means for supporting said knives on said shaft, soil diggingmeans disposed on 'the last mentioned means, and means for actuatingsaid shafts.

2. In a device of the class. described, a shaft, a plurality of spirallydisposed knives, a plurality of standards on said shaft for supportingsaid knives, said standards having sharpened ends arranged to engagewith the soil and provide furrows for the knives to follow into, andmeans for actuating said shafts.

3. In a device of the class described, a

shaft, standards secured to said shaft and projecting perpendicularlytherefrom and formed with obliquely disposed and laterally turned endswith pointed --extremities,

and spiral knives secured to the obliquely disposed ends of thestandards;

In testimony whereof I hereunto afiix my signature in the presence oftwowitnesses. JAMES S. LYNCH. Witnesses:
